causes, not reasons

Some coincidence are imposible.

Yes, and sometimes the reason is that you made a bad decision.

The end state is pre-determined. How you get there depends on you.

If it happens for a reason, is it a simulation?

Yes, but the reason might be to teach you that you’re not entitled to know every reason. Which is itself a pretty good reason.

everything is cause and effect, but there is no grand plan
